GAGE-COCK.

Application filed December 7, 1918.

To all whom it may concern:

Be it known that I, CLYDE S. WRIGHT, a citizen of the United States, residing at T0- ledo, in the county of Lucas and State of Ohio, have invented new and useful Improvements in Gage-Cocks, of which the fo1- lowing is a specification.

My invention relates to gage-cocks of the weight-valve type for steam boilers.

It is the object of this invention to provide a gage-cock which is simple in construction and cheap to manufacture. Another object is to provide a gage-cock having a magazine containing a stack of packing disks fed by a plunger and capable of being refilled without removing the weight or extracting any of the packing.

The figure on the accompanying drawing is a central longitudinal section of a gagecock constructed according to the principles of this invention.

On the drawing, 1 represents the shank having the end 2 threaded for insertion in an opening in a boiler. The other end of the shank has on its upper side the forwardly projecting lug 3, to which the weightvalve 4 is connected by the pivot or pin 5. The shank has a central longitudinal opening 6 extending entirely through it, the outer end of the opening being in the convex valveseat 7 on the forward end of the shank.

The weight-valve 4 has a central longitudinal opening extending entirely through it and arranged to be in alinement with the opening 6 when the weight-valve is horizontal or in line with the shank, as shown on the drawing. The inner portion 8 of the opening contains a liner 9 forming a magazine for the disks 10 of packing. The outer portion 11 of the opening is screw-threaded to receive the threaded portion 12 of the plunger or feed-screw 13 having its inner end preferably smooth and working in the magazine 9. 14 is a hand-wheel for rotating the plunger. The liner and the body of the weight-valve may, if desired, be made in a single piece.

Between the top of the magazine 9 and the threaded portion 11 of the weight-valve, I make the lateral opening 15 extending from the exterior of the weight-valve to the central opening therein.

Specification of Letters Patent.

Patented July 15, 1919.

Serial No. 265,694.

The plunger 13 is turned up against the outermost disk 10 in the stack until the innermost disk 10 will be seated squarely on the seat 7 when the weight-valve 4 is in its horizontal position, as shown on the drawing. In this position the weight of the weight-valve closes the opening 6.

When a packing disk next to the valveseat becomes unfit for further use, the weight-valve is swung up on the pin. 5 and the plunger 13 turned until that packing disk is ejected from the magazine and the next packing disk is brought into the proper position, whereupon the weight-valve is lowered to the position shown. When it is desired to refill the magazine 9, the weightvalve is raised to the vertical position, the plunger is removed, the magazine is filled through the opening 15, the plunger re turned to its position, and the weight-valve is returned to its horizontal position.

I claim 1. In a gage-cock, a shank having a longitudinal opening, a valve pivoted to the shank and having in its inner end a magazine for holding packing against the outer end of the said opening in the shank, there being a feed-opening in the side of the valve for the insertion of packing into the magazine, and means for feeding the packing through the magazine.

2. In a gage-cock, a shank having a longi tudinal opening, a valve pivoted to the shank and having in its inner end a magazine comprising a tubular liner for holding packing against the outer end of the said opening in the shank, there being a feedopening in the side of the valve for the in sertion of. packing into the magazine, and means for feeding the packing through the magazlne.

3. In a gage-cock, a shank for insertion into a boiler wall, having a longitudinal opening terminating in a valve-seat, a weight-valve pivoted to the shank so as to be swung into and out of alinement with the shank and having a longitudinal opening in alinement with the opening in the shank when the weight-valve and shank are in alinement, and a power plunger working in the said opening in the weight-valve and arranged to feed packing along the inner end of the said opening, there being a lateral zine and an opening in the side thereof for opening in the Weight-valve for the inserthe insertion of packing into the magazine. tion of packing into the said longitudinal Signed at Toledo, Ohio, this 2nd day of opening of the Weight-valve. December, 1918.
